You know that you can lookup the url of a ressource by opening the 3-dots menu behind e.g. a calendar and choosing properties? That’s not exactly what you asking for but a workaround. I would assume that the base url is usually the part in front of the user name.
I’d like to ask if you could add some more intervals for syncing. The 1st hour should have more steps to choose, e.g. 5, 10, 15, 30, 45 minutes.
Please find attached a patch. I didn’t compile it and did it in theory.
Thanks a lot for considering it.
